While many banks nowadays attempt to associate themselves with a values-based lifestyle, the Permaculture Credit Union (PCU) puts those other greenback hoarders to shame. To be a member of the PCU, you've got to have sustainability cred; its members are those dedicated to "care of the earth, care of people, and reinvestment of the surplus to benefit the earth and its inhabitants." In short, the PCU is a kind of grassroots, community-based loan fund that supports environmental sustainability.
